Answer:

x = 5, y = 1/2

Step-by-step explanation:

-3x - 4y = -17   Use the elimination method by adding the 2 equations together

5x+4y=27​

2x = 10   ===> x = 5

3(5) + 4y = 17,

4y = 2    ===> y = 1/2

Shaun drew ΔLMN, in which m∠LMN = 90°. He then drew ΔPQR, which was a dilation of ΔLMN by a scale factor of 3 from the center of
Tatiana [17]

Answer:

Step-by-step explanation:

we have ΔLMN as our parent triangle, where M=90°. Another triangle ΔPQR is formed which was dilation of ΔLMN with a factor of one and half that is 1.5

We are also given that the center of dilation is M itself . Hence the point Q of the ΔPQR overlap with the M.  

Now let us see the image attached with this. The Line LM and MN are extended further till Point P and R respectively.  

If LN = x and MN = y  

PM = 1.5x and MR = 1.5y  

as the scale of dilation is 1.5

Now let us see the the ratio of the sides of the two triangles.

Hence the ratio of the sides is same. There for the triangles are similar to each other.

A recipe calls for got to go to 32 fluid ounces of heavy cream how many 1 pint containers of heavy cream are needed to make the
Ne4ueva [31]

There are 8 fluid ounces in a cup. There are 2 cups in every pint. So every pint container can hold 16 fluid ounces of heavy cream.

If you take the total of 32 and divide it by 16 (the number of ounces a pint container can hold), you get 2 which is the number of pint containers you need to get 32 fluid ounces
